## II. Self-Regulatory Organization's Statement of the Purpose of, and Statutory Basis for, the Proposed Rule Change

In its filing with the Commission, the Exchange included statements concerning the purpose of and basis for the proposed rule change and discussed any comments it received on the proposed rule change. The text of these statements may be examined at the places specified in Item IV below. The Exchange has prepared summaries, set forth in sections A, B, and C below, of the most significant aspects of such statements.

### A. Self-Regulatory Organization's Statement of the Purpose of, and Statutory Basis for, the Proposed Rule Change

#### 1. Purpose

Phlx proposes to amend Options 3, Options Trading Rules, at: Section 7, Types of Orders and Order and Quote Protocols; Section 8, Options Opening Process; Section 10, Electronic Execution Priority and Processing in the System; Section 12, Electronic Qualified Contingent Cross Order; Section 13, Price Improvement XL (“PIXL”); Section 14, Complex Orders; Section 23, Data Feeds and Trade Information; Option5, Section 4, Order Routing; and Options 7, Section 3, Rebates and Fees for Adding and Removing Liquidity in SPY. The Exchange also proposes to amend its Rules at Options 8, Floor Trading, at: Section 30, Crossing, Facilitation and Solicited Orders; and Section 32, Types of Floor-Based (Non-System) Orders.

#### Background

                    Today, Phlx's All-or-None Orders are described in Options 7, Section 7(b)(5) as Limit Orders or Market Orders that are executed in their entirety or not at all. All-or None Orders may only be submitted by a Public Customer.[3]                                          Phlx's All-or-None Orders rest on the order book as non-displayed orders. The Exchange does not disseminate bids or offers of All-or-None Orders to the Options Price Reporting Authority or “OPRA” and Top of PHLX Options [4]                                          feed, however All-or-None Orders are displayed in the PHLX Orders [5]                                          and PHLX Depth of Book [6]                                          feed. Further, All-or-None Orders are executed in price-time priority among all Public Customer orders if the size contingency can be met. If an All-or-None Order contingency cannot be met, the All-or-None Order would be by-passed until such time as the contingency could be met.[7] 

#### Proposal

                    At this time, the Exchange proposes to amend All-or-None Orders so that they may only be submitted by a Public Customer as an Immediate-or-Cancel Order. With this proposed change, All-or-None Orders would no longer rest on the order book. Upon entry, an All-or-None Order would be executed in its                           ( print page 57141)                        entirety or it will cancel if it cannot execute. Other options markets require All-or-None Orders to be Immediate-or-Cancel such as Nasdaq GEMX, LLC.[8] 

The Exchange proposes to amend the order type description in Options 3, Section 7(b)(5) to state, “An All-or-None Order is a Limit Order or Market Order that is to be executed in its entirety or not at all. An All-or None Order may only be submitted by a Public Customer as an Immediate-or-Cancel Order.” As is the case today, the Acceptable Trade Range protection in Options 3, Section 15(a) is not applied to All-Or-None Orders. Further, the All-or-None Order type in Options 8, Section 32(b)(3) may only be submitted by a Public Customer. The Exchange proposes to add a new sentence in Options 8, Section 32(b)(3) that would state, “Further, pursuant to Options 8, Section 39, A-3, an All-or-None Order has no standing respecting executions in the trading crowd except with respect to other All-or-None Orders. When represented in the trading crowd, All-or-None Orders are not included as part of the bid or offer.” The Exchange believes the new sentence, which references existing language in Options 8, Section 39, A-3, will bring greater clarity to the All-or-None Order type description.

The Exchange proposes to also remove rule text about All-or-None Orders as a Non-Displayed Contingency Order in Options 3, Section 7(b)(5)(i). The Exchange proposes to add a new Options 3, Section 7(b)(4)(C) that states, “A Stop Order is a non-displayed, contingency order until elected,” in order to preserve the current rule text related to Stop Orders at Options 3, Section 7(b)(5)(i).

As a result of the proposed amendment to the All-or-None Order type, Phlx proposes to remove rule text regarding All-or-None Orders in various other rules. Since All-or-None Orders will not rest on the order book, it is not considered for purposes of Legging Orders and therefore the rule text within Options 3, Section 7(b)(10)(2) and (4) related to All-or-None Orders is being removed. Additionally, the Exchange proposes a technical amendment to re-letter Options 3, Section 7(b)(1) (1)-(4) as (A)-(D).

Since All-or-None Orders will not rest on the order book as proposed, those orders would be treated the same as all other Immediate-or-Cancel Orders in the Opening Process and, therefore, do not need to be separately described in Options 3, Section 8. The Exchange proposes to remove specific references to All-or-None Orders in Options 3, Section 8(b), (h) and (k)(C)(6).

All-or-None Orders do not need to be excluded from the internal PBBO in Options 3, Section 10, which describes the Exchange's allocation process, because All-or-None Orders will not rest on the order book with this proposed amendment. The Exchange proposes to remove the language concerning All-or-None Orders from Options 3, Section 10(a)(1)(B), (C), and (D)(i) and (ii).

As proposed, Public Customers All-or None Orders, similar to all other Public Customer Orders which are Immediate-or-Cancel Orders, will not be considered for purposes of checking the order book prior to executing a Qualified Contingent Cross Order since they will not rest on the order book. Therefore, the Exchange proposes to remove the language within Supplementary Material .01 to Options 3, Section 12 and Options 8, Section 30 concerning All-or-None Orders.

As proposed, All-or None Orders will not be considered when checking the order book to start a PIXL Auction or to allocate the PIXL Order at the end of the PIXL Auction because All-or-None Orders will not rest on the order book. Therefore, the Exchange proposes to remove the language within Options 3, Section 13(a)(2) and (f) related to All-or-None Orders on the order book.

As amended, All-or-None Orders will be treated in the same manner as other Immediate-or-Cancel Orders with respect to a Complex Opening Process and a Complex Order Live Auction. Also, All-or-None Orders will not rest on the order book and are not considered for purposes of legging into the simple order book. Therefore, the Exchange is removing language concerning All-or-None Orders within Options 3, Section 14(d)(ii)(C), (e)(vi)(A)(1), (e)(viii)(C)(3), and (f)(iii)(A) because All-or-None Orders do not need to be treated differently.

For purposes of the PHLX Orders feed, All-or-None Orders will be treated the same as all other Immediate-or-Cancel Orders and not displayed on the PHLX Orders feed. Options 3, Section 23(a)(2) is being amended to remove All-or-None Orders from the feed description.

Since All-or-None Orders will not rest on the order book the Exchange proposes to amend Options 5, Section 4(a), 4(a)(iii)(C)(3), (5), (7) and (9), concerning Routing, to remove references to the exclusion of All-or-None Orders from the PBBO and their partial exclusion from the internal PBBO.

                    The Exchange proposes to remove the following pricing from Options 7, Section 3, Rebates and Fees for Adding and Removing Liquidity in SPY, “The Cancellation Fee for each cancelled electronically delivered Professional [9]                                          AON order will continue to apply to the SPY. The Cancellation Fee will not apply for each cancelled electronically delivered Customer order in SPY.” Today, only Public Customers may submit All-or-None Orders.[10]                                          In 2019, Phlx amended its All-or-None Order type to offer it only to Public Customers and no longer offer the order type to Professionals.[11]                                          This pricing should have been removed in 2019, as Professionals could no longer enter All-or-None Orders after the 2019 amendment.                

#### Implementation

The Exchange proposes to implement this rule proposal before January 31, 2024. The Exchange will announce the implementation date in an Options Trader Alert to provide notice to members and member organizations.

#### 2. Statutory Basis

                    The Exchange believes that its proposal is consistent with Section 6(b) of the Act,[12]                                          in general, and furthers the objectives of section 6(b)(5) of the Act,[13]                                          in particular, in that it is designed to promote just and equitable principles of trade, to remove impediments to and perfect the mechanism of a free and open market and a national market system, and, in general to protect investors and the public interest.                

                    The Exchange believes that the proposal is appropriate and reasonable, because the time-in-force designation of Immediate-Or-Cancel will offer members and member organizations certainty with respect to their order handling. Today, All-or-None Orders are executed in price-time priority among all Public Customer orders if the size contingency can be met, but otherwise                           ( print page 57142)                        have no priority on the order book. With this proposal, an All-Or-None Order will either execute immediately or be cancelled back to the member or member organization. This proposal would remove uncertainty with respect to the manner in which these orders would be handled in the order book by cancelling back an All-Or-None Order if it cannot be immediately executed in its entirety. This proposal would harmonize Phlx's All-or-None Order type across its various options markets.[14] 

                    The Exchange notes that members and member organizations are aware of this proposed change.[15] 

### B. Self-Regulatory Organization's Statement on Burden on Competition

                    The Exchange does not believe that the proposed rule change will impose any burden on competition not necessary or appropriate in furtherance of the purposes of the Act. The Exchange does not believe that the proposed rule change will impact the intense competition that exists in the options market. With this change, no market participant would be able to submit an All-Or-None Order without a time-in-force designation of Immediate-Or-Cancel. The Exchange believes the All-Or-None Order type, as proposed, will continue to offer members and member organizations a competitive alternative for submitting orders for execution. Furthermore, the proposed rule changes align the Exchange's System functionality across the Nasdaq affiliated options exchanges that have all-or-none order types.[16] 

### C. Self-Regulatory Organization's Statement on Comments on the Proposed Rule Change Received From Members, Participants, or Others

No written comments were either solicited or received.

## III. Date of Effectiveness of the Proposed Rule Change and Timing for Commission Action

                    Because the foregoing proposed rule change does not: (i) significantly affect the protection of investors or the public interest; (ii) impose any significant burden on competition; and (iii) become operative for 30 days from the date on which it was filed, or such shorter time as the Commission may designate, it has become effective pursuant to section 19(b)(3)(A)(iii) of the Act [17]                                          and subparagraph (f)(6) of Rule 19b-4 thereunder.[18] 

At any time within 60 days of the filing of the proposed rule change, the Commission summarily may temporarily suspend such rule change if it appears to the Commission that such action is necessary or appropriate in the public interest, for the protection of investors, or otherwise in furtherance of the purposes of the Act. If the Commission takes such action, the Commission shall institute proceedings to determine whether the proposed rule should be approved or disapproved.

## IV. Solicitation of Comments
